sorry for off-topic
what is the actual performance scale from that overclocking compered to stock clocks?

This is using my cards at stock, cannot turn off "GPU Boost", so they OC dynamically based on the TDP, but I didn't adjust anything else, except for the CPU clock for comparison's sake being at 4.8Ghz:

EDIT: Just realized the picture I uploaded was for a run done at 4200Mhz instead of 4800Mhz for the CPU, this new screen shot corrects that error and should provide a more fair comparison to the VGA OCd results

I'm getting two new 680s when availability stabilizes, i'm using my EVGA Step Up from my 480s, I have a question for you, I take it you're using two PSUs to power your four cards, I've never done that, can you tell me how to synchronize two PSUs? Thank you very much!

Thanks MetalRacer, I've been contemplating this question for a while now, as I'm in queue for my step up as inventory is very limited right now, but I'll get this adapter while I wait for EVGA to send me the new cards.

Thanks but I don't see how these settings are helping him.... I have tried higher clocks then him... and have not got a score as high as 18K with almost an exact same setup. I'm confused how he is getting that score with 2 HD7970's Water cooled and a i7 @ 5ghz I would like to know his settings
